I have some large .mov files that I'm trying to convert to .mp4. As the original .mov files they look fine if I play them in either Quicktime or VLC Media Player.
However, if I load them into Sony Vegas to re-render them as some other format the video doesn't show, just the audio track. If I convert them with something like Wondershare or the like I get the same results.
Does anyone think it is the .mov file itself, or is there something about the conversion that's goofy? How can I convert these?
